[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following will be combined with Figures 1-4 Describe the motor damping mechanism according to an embodiment of the present invention.

[0031] The motor vibration damping mechanism according to an embodiment of the present utility model includes a mounting bracket 1 and a vibration damping member 2. The motor 3 is mounted on the vibration damping member 2. One of the mounting bracket 1 and the vibration damping member 2 includes a main body 11 and a plurality of discretely arranged feet 12. The plurality of feet 12 are arranged at intervals on one side of the main body 11 in the height direction. The other of the mounting bracket 1 and the vibration damping member 2 is connected to the plurality of feet 12 and is spaced apart from the main body 11.

[0032] In the motor vibration damping mechanism according to an embodiment of the present utility model, the main body 11 on one of the vibration damping member 2 and the mounting bracket 1 is connected to the other through the feet 12, so that the main body 11 is spaced apart from the other. The arrangement of the feet 12 can effectively reduce the vibration transmission area between the vibration damping member 2 and the mounting bracket 1, making the vibration transmission area smaller than the end face area of the motor 3. Furthermore, when the motor mounted on the vibration damping member 2 works, it is less likely to cause resonance between the vibration damping member 2 and the mounting bracket 1 and generate large noise, and the user experience is good.

[0033] It should be noted that both the mounting bracket 1 and the vibration damping member 2 are injection molded parts. The vibration damping member 2 is tightly connected to the motor 3. There are at least three feet 12, and there are always three feet 12 arranged in a triangle.

[0034] In some embodiments, as Figure 2 and Figure 4 shown, the mounting bracket 1 includes a main body 11 and feet 12. The feet 12 are arranged on the side of the main body 11 facing the vibration damping member 2. The vibration damping member 2 includes a base plate 21. The base plate 21 is connected to the plurality of feet 12 and is spaced apart from the main body 11. The motor 3 includes a housing 31. The housing 31 is mounted on the side of the base plate 21 facing away from the feet 12.

[0035] That is, the housing 31 does not directly contact the main body 11 and the feet 12 of the mounting bracket 1. Thereby, the vibration transmission area between the housing 31 and the vibration damping member 2 as a whole and the mounting bracket 1 is further reduced, and the probability of resonance between the vibration damping member 2 and the mounting bracket 1 is further reduced. The noise generated when the motor 3 works is lower, and the user experience is better.

[0036] Specifically, the housing 31 is connected to the base plate 21 through two connecting flanges thereon.

[0037] In some embodiments, as Figure 4 shown, the feet 12 are located above the main body 11 and extend in the height direction. The vibration damping member 2 further includes a guide sleeve 24 extending downward from the lower end surface of the base plate 21. The feet 12 are fitted in the guide sleeve 24.

[0038] Through the cooperation of the feet 12 and the guide sleeve 24, the relative fixation of the base plate 21 and the main body 11 in the radial direction of the guide sleeve 24 is effectively ensured. The connection strength between the base plate 21 and the main body 11 is higher, and at the same time, the assembly efficiency of the vibration damping member 2 on the mounting bracket 1 is also improved.

[0039] Specifically, the outer contour of the cross section of the support leg 12 is circular, the inner and outer contours of the cross section of the guide sleeve 24 are both circular, and the upper end of the support leg 12 is inserted into the guide sleeve 24 and abuts against the lower end surface of the base plate 21. In order to further reduce the contact area between the vibration damping member 2 and the mounting bracket 1, the cross-sectional area of ​​the support leg 12 is set as small as possible in this embodiment, and the number of the support legs 12 is preferably three and arranged in a triangle.

[0040] In some embodiments, Figure 4 As shown, the vibration reduction mechanism of the motor 3 also includes a threaded member, a threaded hole 121 is provided on the upper end surface of the support foot 12, a first mounting hole 211 communicating with the inner cavity of the guide sleeve 24 is provided on the base plate 21, and the threaded member passes through the first mounting hole 211 and is threadedly matched with the threaded hole 121.

[0041] Thus, the connection between the base plate 21 and the support leg 12 is convenient and reliable, and other vibration transmission areas are avoided between the vibration damping member 2 and the mounting bracket 1, further reducing the probability of resonance between the vibration damping member 2 and the mounting bracket 1.

[0042] Specifically, two connecting flanges are provided on the outer peripheral surface of one end of the casing 31 adjacent to the mounting bracket 1, and a second mounting hole is provided on the connecting flange. The number of first mounting holes 211 on the substrate 21 is three, and the threaded members are bolts, two of which pass through the two second mounting holes and two of the first mounting holes 211 respectively and are threadedly connected to the threaded holes 121, and the remaining bolt passes through the remaining first mounting hole 211 and is threadedly connected to the remaining threaded hole 121, thereby realizing the installation of the motor 3 on the substrate 21 and the connection between the substrate 21 and the support leg 12, and the assembly efficiency of the vibration damping member 2, the mounting bracket 1 and the motor 3 is higher.

[0043] In some embodiments, Figures 1-3 As shown, the vibration damping member 2 further includes a side plate 22 , which is connected to a side of the base plate 21 away from the mounting bracket 1 , and the side plate 22 abuts against a portion of the wall surface of the housing 31 .

[0044] That is, the vibration damper 2 abuts against the wall surfaces of the housing 31 at different angles through the base plate 21 and the side plate 22, and the vibration damper 2 limits the housing 31 in the height direction and the horizontal direction. The connection between the vibration damper 2 and the housing 31 is tighter, and it is less likely to resonate and generate noise. It also effectively supports the housing 31, thereby effectively improving the overall rigidity of the motor 3.

[0045] Specifically, the base plate 21 is disposed on the upper end surface of the base plate 21 , and the thickness direction of the base plate 21 is perpendicular to the thickness direction of the side plate 22 .

[0046] In some embodiments, Figures 1-3As shown, the axial direction of the housing 31 is consistent with the thickness direction of the substrate 21. The side plate 22 extends along the circumferential direction of the housing 31. The side plate 22 and the substrate 21 surround to form a receiving cavity. At least a part of the housing 31 is arranged in the receiving cavity, and the end face of the housing 31 is in close contact with the side of the substrate 21 away from the support leg 12.

[0047] Thus, the damping member 2 has higher support reliability for the housing 31 in its axial and radial directions, and the mounting strength of the motor 3 on the motor damping mechanism is higher.

[0048] In some embodiments, as Figure 2 and Figure 3 shown, the dimension of the side plate 22 in the thickness direction of the substrate 21 is smaller than the dimension of the housing 31 in the axial direction of the housing 31.

[0049] At this time, while the side plate 22 can achieve radial limiting of the housing 31, the size of the damping member 2 can be effectively reduced, and the manufacturing cost of the damping member 2 is lower. At the same time, this setting also ensures that a larger area of the housing 31 is exposed to ensure the heat dissipation efficiency and working performance of the motor 3.

[0050] Specifically, the height of the side plate 22 is equal to or slightly greater than half of the height of the housing 31.

[0051] In some embodiments, a plurality of spaced-apart limiting ribs 23 are provided on the side of the side plate 22 facing the housing 31, and the side plate 22 abuts against a part of the wall surface of the housing 31 through the plurality of limiting ribs 23.

[0052] This setting effectively reduces the contact area between the side plate 22 and the housing 31. While meeting the reliable support for the housing 31 in its radial direction, it also effectively reduces the probability of resonance between the housing 31 and the side plate 22, and the noise generated during the operation of the motor 3 is lower.

[0053] Specifically, the limiting ribs 23 and the side plate 22 are integrally injection-molded.

[0054] In some embodiments, as Figure 1 and Figure 3 shown, the axial direction of the housing 31 is consistent with the thickness direction of the substrate 21, the limiting ribs 23 extend along the thickness direction of the substrate 21, and the plurality of limiting ribs 23 are arranged at intervals along the circumferential direction of the housing 31.

[0055] That is, the extending direction of the limiting ribs 23 is consistent with the extending direction of the side plate 22, which facilitates the integral injection molding of the damping member 2 and effectively reduces the manufacturing cost of the damping member 2.

[0056] Specifically, the plurality of limiting ribs 23 are arranged at equal intervals along the circumferential direction of the housing 31.

[0057] Alternatively, the limiting ribs 23 can also be in the form of bump structures, and the limiting ribs 23 are uniformly and discretely arranged on the side of the side plate 22 facing the housing 31.

[0058] Specifically, the side plate 22 and the base plate 21 surround the accommodating cavity with an opening opposite to the mounting bracket 1, and part of the housing 31 fits in the accommodating cavity. The side plate 22 is also provided with a notch connected to the accommodating cavity, the notch is oriented in the radial direction of the housing 31, and the controller installed outside the housing 31 fits in the notch.

[0059] In some embodiments, the motor vibration reduction mechanism further includes a buffer layer (not shown in the figure), the hardness of the buffer layer is lower than the hardness of the limiting rib 23, and the buffer layer is connected to the side of the limiting rib 23 away from the side plate 22. And / or, the buffer layer is connected to the outer peripheral surface of the housing 31, and the limiting rib 23 abuts against the outer peripheral surface of the housing 31 through the buffer layer.

[0060] The buffer layer can better absorb the impact from the housing 31 and effectively avoid the rigid collision between the limiting rib 23 and the housing 31 to generate noise by eliminating the gap between the limiting rib 23 and the housing 31 .

[0061] Specifically, the buffer layer may be bonded to the limiting rib 23 and / or the housing 31 .

[0062] In some embodiments, the buffer layer includes any one of flannel, rubber and sponge, all of which can effectively absorb the impact from the housing 31, are easy to purchase, and effectively reduce the manufacturing cost of the motor vibration reduction mechanism.

[0063] For example, the buffer layer is flannel, which is bonded to the outer peripheral surface of the housing 31 .

[0064] In some embodiments, Figure 2 As shown, the motor shaft of the motor 3 is transmission-connected to the swing arm 4, one of the body 11 and the swing arm 4 is provided with a guide hole 41, the guide hole 41 is coaxial with the motor shaft, and the other of the body 11 and the swing arm 4 is provided with a guide column 11, which fits in the guide hole 41.

[0065] That is, when the motor 3 drives the swing arm 4 to swing via the motor shaft, the guide column 11 cooperates with the guide hole 41, so that the mounting bracket 1 also has a reliable limit on the end of the swing arm 4 adjacent to the motor shaft in the radial direction of the motor shaft, thereby effectively reducing the radial load on the housing 31 when the motor 3 is working, and the connection between the housing 31 and the mounting bracket 1 is less likely to be worn or shaken due to excessive impact. The probability of resonance between the motor 3 and the mounting bracket 1 through the vibration damping component 2 is lower, and the motor 3 generates less noise when working.

[0066] Specifically, Figure 2 As shown, a guide column 11 is provided on the side of the body 11 facing the motor shaft, and a guide hole 41 is provided on the side of the swing arm 4 facing away from the housing 31 . The swing arm 4 is rotatably sleeved on the guide column 11 through the guide hole 41 .
